[Puppet Users] Augeas fails to set BONDING_OPTS with return code false

I'm attempting to manage my network interfaces through a homebrew module
that takes input from hiera, and then uses augeas to define each ifcfg-*.

Example:
/* Set manditory parameters */
augeas { "eth_bond_${name}" :
context => "/files/etc/sysconfig/network-scripts/ifcfg-${name}",
changes => [
"set DEVICE ${name}",
"set BONDING_OPTS '\"mode=${mode} miimon=${miimon}\"'",
"set BOOTPROTO none",
"set USERCTL no",
"set ONBOOT yes",
"set MTU ${mtu}",
"set IPADDR ${ip}",
"set NETMARK ${netmask}",
],
notify => Exec["if-refresh-${name}"],
}


When I try and set something like BONDING_OPTS="mode=0 miimon=100" I get
the following in Puppet

debug: Augeas[eth_bond_bond0](provider=augeas): Opening augeas with root /,
lens path , flags 0

I also can't seem to get that value saved using augtool either, here's what
I get

# cat ifcfg-bond0
BOOTPROTO=none
ONBOOT=yes
MTU=4000
IPADDR=192.168.1.100
NETMARK=255.0.0.0
DEVICE=bond0

# augtool
augtool> set /files/etc/sysconfig/network-scripts/ifcfg-bond0/BONDING_OPTS
'\"mode=0 miimon=100\"'
augtool> save
error: Failed to execute command
error: saving failed (run 'print /augeas//error' for details)

/augeas/files/etc/sysconfig/network-scripts/ifcfg-bond0/error/path =

/augeas/files/etc/sysconfig/network-scripts/ifcfg-bond0/error/lens =
"/usr/share/augeas/lenses/dist/shellvars.aug:61.12-.77:"
/augeas/files/etc/sysconfig/network-scripts/ifcfg-bond0/error/message =
"Malformed child node 'BONDING_OPTS'"

Any ideas? The documentation on Puppet Augeas (
http://projects.puppetlabs.com/projects/1/wiki/Puppet_Augeas#ifcfg+BONDING_OPTS)
has this exact example, so I figured there's something very obvious I'm
overlooking that's keeping this from working.

Currently affected host and Puppet master are 2.6.16, CentOS 6.2,
augeas-0.9.0.

Thanks
